Abstract
Surgical resection of intrahepatic cholangiocarcinoma with major vascular and atrial invasion is
described in this case report using cardiopulmonary bypass followed by complex vascular
reconstruction.

Introduction
Cholangiocarcinoma is a primary hepatic tumor that arises from the biliary ductal epithelium.
Early symptoms are uncommon unless it occurs at or distal to the hepatic duct bifurcation, so
many patients present with large, often unresectable tumors. Here we report the case of an
intrahepatic cholangiocarcinoma invading the suprahepatic inferior vena cava (IVC) and right
atrium, along with our surgical approach and technique for reconstruction.
Case Presentation
A 47 year-old woman was incidentally found to have a liver mass during workup for an
asymptomatic umbilical hernia. Computed tomography of the abdomen and pelvis
demonstrated a non-enhancing 3 cm mass in the left aspect of the caudate lobe of the liver. This
mass was adjacent to the inferior vena cava and appeared to invade the left hepatic vein and
extend superiorly to the right atrium.

The patient was referred for surgical resection. The operation was performed with a team of
hepatobiliary and cardiothoracic surgeons. First, abdominal exploration was done through a
bilateral subcostal incision with midline extension. Upon palpation, the tumor invaded the
suprahepatic IVC, the surrounding diaphragm, and extended into the right atrium. A left
hepatectomy, including caudate lobe resection, starting with parenchymal transection was
performed, leaving only the left and middle hepatic veins attached to the IVC. Next, a median
sternotomy was performed, the cava were snared, the liver vascular inflow was controlled with a
vascular clamp. The patient was placed on cardiopulmonary bypass with the inferior vena cava
cannula inserted distal to the hepatic veins, the superior cava cannulated through the right atrial
appendage, and the arterial cannula in the ascending aorta. The cava was then opened 1 cm
caudal to the entrance of the left hepatic vein. The tumor was palpated superiorly past the
atriocaval junction. The inferior portion of the right atrium was resected 2 mm below the

coronary sinus. The entire en bloc specimen was then removed from the operative field, which
included the left lobe and caudate lobe of the liver, IVC, diaphragm, and right atrium (Figure 1).

The atriocaval junction was then reconstructed using 34 mm Hemashield tube graft (Boston
Scientific, Natick, MA) (Figure 2).

was resected 2mm below the coronary sinus.
The inferior part of the graft was tailored to the preserved back wall and distal inferior vena cava
just above the cannula. When this was completed, the patient was easily weaned from bypass and
decannulated. The diaphragm was then reconstructed using Gore-Tex mesh (Gore, Tempe, AZ).
The patient’s postoperative course was uneventful. Ultrasound of the liver demonstrated graft
patency, and the patient was placed on low molecular-weight heparin to prevent thrombosis of
the graft. Final pathology revealed infiltrating, poorly differentiated cholangiocarcinoma
invading the left hepatic vein and extended through liver capsule and diaphragm into the wall of
the right atrium.
Discussion
Surgical resection is the gold standard for cholangiocarcinoma. While chemotherapy, external
beam radiation, and a combination of the two have been studied, there has not been compelling
evidence to support the use of these modalities outside of a trial setting [1]. Some specialized
centers have taken an aggressive surgical approach to tumors that invade adjacent vascular
structures, and extended hepatic resections with caval reconstruction have been successfully
performed [1,2]. Five-year survival for intrahepatic cholangiocarcinoma ranges from 8% to 47%,
depending upon the ability to achieve negative (R0) margins [1]. Lang et al. have achieved a
median survival of 46 months with a calculated one- and three-year survival rate of 94% and
82%, respectively, for R0 resection [2]. However, the median survival drops to five months for R1
resection (microscopic tumor at margins), and the calculated one-year survival is 22%. Stage
greater than I, multifocality, lymph node involvement, and vascular invasion are poor prognostic
factors [2].

Intracardiac extension of hepatic tumors presents an even greater challenge to resectability.
There are some advanced cases that have presented with Budd-Chiari syndrome [3,4]. While
there are scant reports in the literature describing the successful resection of hepatocellular
carcinoma with extension to the heart, there is no such documentation for cholangiocarcinoma
[4-7]. Removal of the tumor without disturbing its integrity precludes traditional methods of
vascular control. Facciuto et al. and Azoulay et al. describe several techniques for the resection
of tumors at the hepatocaval confluence, including total vascular exclusion with
transdiaphragmatic intrapericardial control of the cava, veno-venous bypass, and in situ
hypothermic perfusion of the liver [8,9]. However, the presence of tumor within a cardiac
chamber requires the application of cardiopulmonary bypass (CPB) for resection. The success of
this technique and its positive impact on survival have been demonstrated in the extirpation of
hepatocellular and renal cell carcinoma [7,10-12]. Invasion of the heart and great vessels by
thoracic malignancies have also been successfully treated with aggressive resection on
cardiopulmonary bypass. Park et al. have shown that the use of CPB itself did not lead to major
morbidity, and that curative resection can be safely achieved [13].
Conclusions
Hepatic tumors with extensive local invasion involving major vascular and cardiac chambers can
be safely resected. The literature supports an aggressive surgical approach and the use of CPB if
the tumor can be completely resected and requires complex vascular reconstruction. Our patient
presented with an intrahepatic cholangiocarcinoma, a tumor whose mainstay of treatment is
surgical resection. A team approach between specialized hepatobiliary and cardiothoracic
surgeons enabled complete extirpation of the tumor.
